Isn't the Web a competitor to the App Store? Especially when web apps start to catch up with native apps (and Santa tracker and the rest of Google's Polymer apps seem to suggest this is only a year or so away, and FirefoxOS has certainly made huge strides in this direction) and offline support with web workers is ubiquitous?
My experiences with Web Components, at least, do seem to suggest they're not very proactive and/or dedicated in the standards department, at least. They did put Shadow DOM into their spec at one point, but then removed it. The template tag is in at least, but that is a very, very simple tag (inert content until added to dom).
(I also found IE11 to play much nicer compared to Safari as compared to bug in my apps, not standard support, although that is really an indication of IE11's quality rather than Safari's laggardly standard support.)
